摘要： A method of failover recording of video streams in a camera connectable to a receiver device over a communication network, the method comprising: detecting that a bandwidth of a connection over the communication network is insufficient for transmitting a video stream at a predetermined bitrate, generating multiple parallel encoded video streams with different bitrates, storing the multiple parallel encoded video streams on a memory storage accessible to the camera, detecting that the memory storage usage of the memory storage exceeds a storage threshold, discontinuing the storing of one of the multiple encoded video streams being the encoded video stream that provides the highest bitrate among the multiple encoded video streams, and discarding the one of the multiple encoded video streams from the memory storage.

摘要： Systems and methods for real-time transmission of data streams are disclosed. A controller receives data representing selected stream parameters from a browser residing on a computing device. The controller transmits the received data to a video transmitting device. A transcoder receives a first data stream generated according to the selected stream parameters from the video transmitting device. The transcoder generates a second data stream from the first data stream, the second data stream formatted for browser display; and then transmits the second data stream to the browser. A user may remotely control the video transmitting device using the browser. A user may view data streams from multiple video transmitting devices using the browser.

摘要： One embodiment of the invention sets forth a mechanism for encoding video streams associated with the same digital content such that switch points staggered across two video streams occur at every offset temporal distance. The offset temporal distance is less than the distance between two consecutive key frames in a given video stream. This enables a content player to switch to a video stream having a playback quality up or down one level from a current video stream at the offset temporal distance from the most recently played key frame. In effect, the content player does not wait the entire key frame temporal distance before switching.

摘要： A statistical multiplexer (statmux) system for encoding multiple channels of digital television data is provided with improved algorithms for determining bitrate for encoding and decoding to account for signal complexity. The variable bit rate (VBR) encoders and encoding are provided in a statmux system by employing a CBR (constant bit rate) adapter. A CBR adapter can provide correcting state updates on a per-frame basis to a CBR encoder element, thereby enabling VBR capability.

摘要： Systems and methods for optimizing a content change process are provided. In example embodiments, a digital receiver causes playback of a first piece of content. The digital receiver receives a selection of a new piece of content for playback during the playback of the first piece of content. In response to the receiving of the selection, the digital receiver maintains a bitrate used for playback of the first piece of content to initiate playback of the new piece of content.

摘要： For transmitting a panorama video having a resolution higher than a decoder can decode, at a transmitter side, encoded data coding different (groups of) spatial segments of a video picture of a video stream are packetized into separate substreams, to obtain a group of separate substreams. At a receiver side, from the group of separate substreams a proper subset of the separate substreams is extracted and combined to a data stream containing encoded data coding respectively a proper subset of the spatial segments or groups of subsequent spatial segments of the video picture of the video stream. Thus, a decoder may decode only a subregion of the video picture of the video stream, the subregion being defined by the spatial segments or groups of spatial segments coded in the encoded data contained in the data stream.
